Aren't ALVIN H. DODD, OF HUDSON, NEW YORK.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 316,131, dated April21, 1835.

Application filed December 29, 1884. (X0 model.)

To (ZZZ whom it mayc0ncern:

Be it known that I, ALVIN H. DODD, of Hudson, in the county of Columbiaand State of New York, have invented a new and useful Improvement inShutter-Workers, of which the following is a'specificatiou,

My invention relates to those shutter-workers in which one member orleaf of the'blind or shutter hinge has formedmpon or connected with it atoothed segment or wheel, and the other member or leafhasjournaled in ita worm or screw which engages with the toothed segment, and has a shaftwhich extends to the inside of the window,and may be there operated by acrank or handle. The operation of the crank or handle turns the worm orscrew, and the latter by its engagement with the toothed segment orwheel, opens and closes the blind or shutter and holdsit in any positionto which it is adjusted.

My invention consistsin novel details of construction and combinationsof parts in a shutter-worker of the kind above described,whereby itsconstruction is oh eapened, and it is rendered more easy of applicationto various window frames, casings, and shutters or blinds, in connectionwith which it is desired to use such a shutter-worker. These features ofnovelty are hereinafter particularly described, and pointed out in theclaims.

In the accompanying drawings, Figure 1 is a horizontal section of aportion of a windowcasing and frame and a shutter, showing my improvedshutter worker applied thereto. Fig. 2 is an inverted plan of the partsof the worker; and Fig. 3 is a vertical section of the parts of theworker on the plane of the dotted line :0 as, Fig. 1.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the shutter or blind. B designates the Window frame andcasing, which is constructed with the usual weight-box, B,and G is thesash. All these parts are of ordinary construction, and G O are theweights which are applied to the lower sash, O, and the upper sash, nothere shown.

D D designate the members or leaves of the hinge, the former, D, beingsecured to the shutter A, and the latter, D, to the window-frame B.These leaves have bearers d d, which are connected bya pivot or pintle,e. The bearer (1,011 the member orleaf D, is cast with a gear or wormsegment or wheel, 01*, upon it, andin the member or leafD isjournaledaworm or screw, E, which engages with the gear or worm segment or wheel(1*. The worm or screw E has a stem orjournal, E, which is fitted to abearing in a hub, (1 projecting outward from the leaf or member D,thereby leaving the inner side or face of the saidleaf or member flat,and requiring no cutting away of the frame. As most clearly shown inFig. 2, the hub d is connected with the bearer d 'bya brace or web, (1",formedintegral with them in casting, and both thehub or bearing d andthe bearer d are thereby strengthened. The worm or screw E should haveat least three threads to the inch,

because if it has less the angle of obliquity of the threads will besuch that the shutter may be turned by force applied'directly to it, andhence may be opened by any one outside the building. The worm or screw Eand its stem or journal E may be made in one piece, either by casting oras a drop-forging.

E designates the worm or screw shaft, which extends to theinner side ofthe window casing and frame B. This must obviously be of a lengthadapted to the depth of the casing and frame, and hence ashaft ofdefinite length cannot be provided for all situations. To provide forthis I make the shaft E of a separate rod joined to the worm-stem orjournal E by a sleeve, E As shown in Figs. 1 and 3, the stem E and shaftE enter opposite ends of the sleeve E and are held therein by pins 9inserted through them, or in any other suitable way. This sleeve E maybe of cast metal.

F designates a flanged bearing, in which the inner end of the shaft E isjournaled,and which may be secured to the inner side of the frame andcasing 13 by screws or other means. To the inner end of the shaft Eadjacent to the bearing F, is secured or may be applied a handle orcrank, G, for turning the shaft and worm to open and close the shutteror blind.

I am aware that it is not new to employ in connection with the twoleaves of a shutterhinge a toothed segment on one hinge-bearer, and aworm or screw journaled in the other leaf, and a shaft for turning theworm or screw extending inward to the inner side of the window-casing,and there provided with a crank. Hence I do not claim, broadly, such ashutterworker as of my invention, and only seek to include thosefeatures of construction and combinations of parts which are hereinabovedescribed, and which enable me to produce a very cheap and simpledevice, which may be applied to window-casings of different depths orthicknesses, and which will not require cutting away or recessing thecasing.

The construction of the leaf D with a flat inner side and anoutwardly-projecting hub, d and the combination therewith' of a wormextending outside of and beyond the hub, and having a stem journaled inthe hub and projecting inward of the inner face of the leaf, enables meto apply the leaf to the casing without any cutting away thereof, and toemploy the shortest possiblelength of worm, and still have an adequatebearing in the leaf.

The construction of the worm with its stem and the crank separate fromthe shaft E and the connection of the shaft and stem by a sleey e andpins, enables me to employ for the shaft 9. heavy wire or light iron rodof any suitable length adapted to the thickness of the windowcasing.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination,with the hinge composed of two leaves, D D, withtheir bearers, one of said bearers having the toothed segment d*,of

the worm E, projecting outside of and beyond the leaf D,and its stem E,projecting inward, through, and beyond said leaf, and having a bearingtherein, the shaft E made separate from the worm and its stem, and thesleeve E made separate from the shaft and worm-stem, and connecting themtogether, substantially as herein described.

2. The combination,with the leaf D,with its bearer d and toothed segment(1*, of the leaf D, with its bearer d and outwardly-projecting hub d theworm E, outside the said hub, and its stem E, journaled in said hub, andprojecting inward beyond the inner face of the leaf D, theoperating-shaft E and the separate sleeve and pins E g, for connectingsaid shaft and the stem E, the bearing F, for the inner end of the shaftE", and the crank or han dle G, made separate from the shaft and securedthereto inside the bearing F, all substantially as herein described.
